Offshore services player Helix Energy Solutions has narrowed its loss in the second quarter of 2017 backed by increased activity of its well intervention business.

On revenue increase of approximately 40 percent year-over-year, the Houston-based well intervention and robotics specialist narrowed its net loss to $6.4 million, or 4 cents per diluted share, against $10.7 million loss, or $10 cents per diluted share in the year-ago quarter.

For the the six months ended June 30, 2017, the company recorded net loss of 16 cents per diluted share, versus net loss of 36 cents per diluted share for the first half of 2016.

Robotics business revenues decreased 13 percent while Helix’s well intervention division generated 88 percent more revenues year-over-year. Sequentially, robotics business generated 50 percent more revenues, and well intervention division some 52 percent.
